1 To all whom it may concern:

' Be it known that I, FRANK J. GnnRqY, a citizen of the United States, residlng at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Car-Doors, of which the following is aspecification, reference being had therein to the accompanyingdrawing. p

My invention relates to doors for cars, such as freight, baggage, and express cars, audits general object is to provide a door that shall-leave available the full space between doors on opposite sides of the 'car, that shall be unusually secure against unauthori zed opening, that shall fully exclude rain.

or the like, andthat shall be proof against the escape of granular material loaded in bulk in direct contact with the doors.

The desired ends are reached by ,provid-' the door with a continuous oblique flange which is overlapped by a similar continuous oblique flange fixed to the car-above the door opening. The door is further provided in its upper half with an opening closed by sliding shutters analogous to the door itself,

- and all parts are securedby devices which cannot be released or removed by unauthorized persons without the car. Still further, the engaging flanges are suchthat pressure within tends to hold closed all crevices at'the joints. a

In the accompanying drawings, Figure 1 shows inelevation the middle-portion of a freight car provided with a metal bound wood door. Fig. 2 is a like view showing a Fig. 3 showsthe inner face of the .door of'Fig. 1. F ig. 4 issimilar door of met-a1.

' a section on the line 4-4=, Fig. 1. Fig. 5

is a section on the line 55, 1., Fig. 6 is a section on the line 6-6, Fig. 1. Fig. 7 is a section;on the line 7-' Fig.1, Fig. 8 is a section on the line 88, Fig. '2. Fig. 9 is a section on the line 9-9, Fig. 2.

The door of Fig. 2 is preferred for new work, butthe devices of Fig. 1 are used to apply the invention with slight expense, to

ordinary cars and their doors.

Inthe last mentioned construction, shown in Figs. 1 and 3 to 7, A represents the body of a car and B of its Wood doors supported by hangers B running in a tubular way C in cross-section. The hooked member B? at all times and the member B when the'door. is closed engage, respectively, metal strips D, D fixed to the car and both concealed and protected when the door is closed. Preferably these members B2B and D, D have no joint at the corners but are bent at the corner point, any joints needed being made in the straight part at some distance from the angle. The left hand member B at the closing margin of the door is not provided with a hook but has a beveled edge and when the door is closed fits under and against a continuous, vertical member D fixed to the car and extending from top to bottom of the door. The member B may be provided on its inner face with a series of wedge-like projections B adapted to imbars'or angle irons B riveted to its external 4 face, and with a pivoted hook 'B at its right hand side to be used in applying opening force. The door is locked by concealed devices not here important and not shown,

and the car is provided with any suitable stops to limit the doors opening} movement. The member B at the upper edge of the door is provided with an upwardly and inwardly extending flange B. which slides longitudinally with the door, beneath a like inclined strip B 'fixed to the car.

"Just/below the hangers, the door is cut away to form a window, or loading opening, which is closed by (as shown in this instance) two sheet metal shutters E, E meeting and overlapping at the middle .of the opening. Each shutter has its upper, lower .and outer marginal portion bent to form a hook E which engages a correspending strip E fixed to the door and concealed when the shuttersare closed. The shutters are secured in closed position by devices on the inside, usually a spring latch It is also obvious that a single shutter may be used, or that but one may be opened when two are employed.

From the construction it follows that when granular bulk material presses against the doors the lower and lateral marginal members of the door are thereby pressed outward firmly against the corresponding members fixed to the car and that no variation in pressure can open any passage for the escape of material. In actual use it has been shown that no amount of rough handling of a grain loaded car, as in switching in making up trains, and in long trips causes any loss whatever. Nor will rain nor even water from a hose cause any material entrance of water. afi'ecting'theclosure of the door can be removed by the use of a wrench or other tool. It is also clear that there is a gain in interior space, equal to the thickness of the car walls, at the door openings, which is a material advantage with baggage and express cars.

The metal door construction shown in Figs. 2, 8', 9'is analogous. the door is made of sheet metal having riveted to its edges similar marginal members N, N, N N and to its face horizontal T bars 0, all the" angles,, preferably, being provided with triangular stiffening webs O integral with or riveted to the marginal members. In this case the shutters P, P are made as before, but preferably their hooked edges engage outwardly turned and hooked marginal portions Q of the plate or body M. The T bars prevent bulging of the doors and with the angle webs serve as braces. In the ordinary car door construction, the shoes are readily removed by any one possessed of a wrench and a pinch bar, and the No parts of the device- The body M of.

lower corner of the door being pried outward and held access to the car is obtained without even breaking the seal. Nothing of the kind is possible with. either form of my invention.

What I claim is:

1. The combination with the usual car door of wood, of U-shaped channel members of metal closely embracing thefour marginal portions of the door, respectively, and provided with integral flanges adapted to engage suitable flanges fixed to the exterior of the car above, below, and at the rear side of the doorway.

2. The combination with a car, of an outwardly projecting external flange alongside the forward lateral margin of the door opening, to receive the door, and a'sliding door adapted to cover said opening and provided upon the inner face of its forward lateral marginal portion with spaced. wedge-like ribs for forcing said door outward against said flange as the'door approaches the limit of its closing movement.

' 3. Thetcombination with a car havingthe usual doorway, of a downwardly'and outwardly inclined flange member bolted to the exterior face of the car wall above the doorway, a downwardly projecting flange member fixed to said face below the doorway, rearwardly turned flange members fixed to said face alon the forward and rear sides respectively, 0 the doorway, a wood door
